What Fairfax Families Are Saying

“I’ve been training with SAPT in Fairfax for two months now, and the experience has been phenomenal. From day one, the coaches have demonstrated incredible professionalism and genuine care—just like the reviews say, “the most passionate people in the strength and conditioning industry”

Their semi‑private training format strikes the perfect balance: personalized programming and expert guidance, yet still with the camaraderie of a group setting. I’m consistently challenged during sessions, and I’ve seen solid gains in strength, movement quality, and overall fitness in a surprisingly short time.

What stands out the most is their attention to detail and individualized approach. Each workout is thoughtfully designed for my goals, and the coaches are always there to correct form, offer encouragement, and adjust the plan based on how I’m progressing.

If you’re serious about getting stronger, moving better, and having great coaches alongside you, I can’t recommend SAPT highly enough. It’s hands-down the best training environment I’ve been a part of—and it shows why they’re consistently ranked top in the area.”

— Grace V.

“SAPT and Hunter have been great to work with. They have really improved our son's performance including adding 3" to his vertical leap. I would definitely recommend them.”

— Dylan O.

“SAPT has been an excellent place for my 14-year-old son to build a strong foundation in fitness and strength training. Having the right guidance and instruction when starting out is so important, especially at a young age. My son is already benefiting from SAPT’s coaching, and I’m confident he’ll continue to build on this new fitness knowledge. I’m excited to see how his training carries forward into hockey season. A big thank you to Hunter and the entire SAPT team!”

— Matt B.

“I am a college athlete, and I started SAPT about a month ago. Hunter and the staff are very supportive and fun! The environment is great—everyone is very welcoming. Having been an athlete my whole life, I can confidently say that SAPT is a great performance facility, and the staff truly wants you to strive to be the best version of yourself!”

— Lindsey N.
